Throughput correction code for offset fibers in SDSS.
python setup.py install
Developer mode:
python setup.py develop
The following packages are used by tpcorr and are installable via pip:
- numpy
- scipy
- matplotlib
- h5py
- astropy
- specsim
- bossdata
The following are optional:
- galsim (more complex PSF models)
bossdata handles interaction with BOSS data including automatic downloading of required data.
The sdss speclog product is also required. Since this is not available via SAS, checkout a local copy of the repo:
svn co https://svn.sdss.org/public/data/sdss/speclog/trunk speclog
And remember to set the BOSS_SPECLOG env var so bossdata knows how to find it.
To calculate corrections for the offset fibers on a given plate-mjd and save them to an hdf5 file use:
tpcorr --plate 6641
For full list of options use tpcorr --help.
